Driver Response to Fog Conditions ? An Intelligent Approach
The Roads and Traffic Authority (RTA) on NSW is currently examining options for replacing its Driver Aid System on the F6 Tollway south of Sydney. On this road drivers are affected by...
Collision Avoidance ? State of the Art
Although crashes are rare events, nearly 40,000 individuals are killed in motor vehicle crashes annually in the US. Another 3 million are injured and the societal costs exceed $137 billion...
Strategic Updating of Autonomous Route Guidance Systems for Air Quality Management
The work in this paper stems from applied research which is implemented as part of the QUARET project. QUARET is a major initiative by four European Community cities. Athens, Birmingham,...
An Integrated Route Assignment and Traffic Simulation System with a Massively Parallel Computing Architecture
This research presents two critical issues in the development of an integrated route assignment and traffic simulation system of ATMS-ATIS applications. The first issue addresses the conceptual...
Simulation of the Dynamic Traffic Flow on Urban Road Network
Methods of performing dynamic traffic assignment are needed to simulate traffic conditions on urban highways during peak periods of congestion. In this paper, the route choice behavior...
An Example of Quantitative Evaluation of AVCS Safety
A method has been devised for expressing in absolute terms the effect on safety of various features in the design of an AVCS system. It depends on gathering data from different sources...
A Framework for ATIS Safety
Advanced Traveler Information Systems utilize advance techniques to acquire, process, and disseminate information to motorists. The main purpose of ATIS is to provide motorists with information...
Establishing a Human Factors Focus and Approach for North Carolina's IVHS Efforts
The paper discusses the behavioral and human factors issues associated with the development and operation of North Carolina's CARAT program (Congestion Avoidance and Reduction for Autos...
Detection of Incidents and Traffic Disturbances in Freeways
This research aims to develop methods for detecting incidents and compression waves through simulation. The detection methods are based on a macroscopic traffic flow model that focuses...
Digital Mapping for Road Navigation in Japan
In Japan, more than 300,000 vehicles are presently equipped with car navigation systems. Development of these systems had been greatly aided by the completion of a standardized digital...
Technology Transfer: Encouraging the Use of Advanced Technologies in Your Organization
Encouraging the evaluation, use, and development of advanced technologies throughout an organization presents a special challenge, with the rewards of successful implementation far outweighing...
Arterial Street Incident Detection Using Multiple Data Sources: Plans for ADVANCE
An Advanced Traveler Information System demonstration called ADVANCE is being prepared for implementation on an arterial street network in the suburbs of Chicago. This paper will describe...
Rain Gage Network Size for Automated Flood Warning Systems
A methodology is presented that establishes a rational framework for estimating the optimum rain gage network size for flash flood warning systems based on network performance and economic...
Selected Precipitation Characteristics in Antelope Valley, Mojave Desert, CA
An urban hydrology study currently in progress in Antelope Valley, California, includes the collection and analyses of precipitation and runoff data. Storms in Antelope Valley are most...
Storm Precipitation in Southwest British Columbia
The storm precipitation in a mountainous watershed in the southwestern British Columbia has been studied. Analysis of the spatial distribution of the storm features showed that the precipitation...
Temporal Variation of Precipitation Trend at Seoul, Korea, 1771-1991
This paper describes temporal variation of annual precipitation trend from 1771 to 1991 at Seoul, Korea. Analysis of the series shows no distinct trend over years. A linear trend would...
Smith's Infiltration Equation and Flooding Infiltrometers
Smith's infiltration equation was developed by examining the output from runs of a physically-based numerical model of one-dimensional infiltration. The model simulated application of...
Scaling Laws of Gravity Driven Fingering During Organic Liquid Infiltration
Wetting front instability can occur during vertical infiltration of a liquid into porous media, particularly when a fine soil layer is overlying a coarse layer. The result of this instability...
Modified Horton Models for Steady Rainfall
When the rainfall rate is less than the initial infiltration rate, direct application of the well-known Horton equation underestimates the total volume of water infiltrating the soil until...
Infiltration in Two Sand Dune Areas in Saudi Arabia
Field infiltration experiments at several locations in two sand dune areas in Saudi Arabia were conducted. Results of these field tests are compared with predictions of the Green and Ampt...
